DavidMac Posted May 21, 2019 Posted May 21, 2019 I am having difficulty understanding what Memory Efficiency in the Info Panel represents. On modest documents this can read as high as 5616%. How can anything be more than 100% efficient? On huge mega documents that make AP really struggle this has plunged to as low as -2147483648% which seems a completely ludicrous and meaningless figure. So please what exactly does Memory Efficiency represent? Quote
Staff Leigh Posted May 23, 2019 Staff Posted May 23, 2019 One of the developers, Andy Somerfield, explains here: Quote Memory Pressure is actually the one you are looking for - once it hits 100%, it means Photo is using the disk.. Memory Efficiency is simply a measure of how well Photo is managing to remove redundancy internally (ie. clone a pixel layer - efficiency will increase - until you start editing pieces of the cloned layer, etc. etc.) I'm guessing the value, -2147483648%, you're receiving is wrong. I will log this with the developers to see why you're getting this. Quote
DavidMac Posted May 23, 2019 Author Posted May 23, 2019 Thanks Leigh. That's clear(ish). I'd sort of guessed the Pressure which is why I was asking about Efficiency. Efficiency sounds like one of those figures of more significance to developers than users. Probably useful if I ever have to come here trying to troubleshoot a memory problem. Leigh 1 Quote
